Abstract

Disclosed is a method of and apparatus for inspecting a printed circuit board (PCB) for the nature of its soldered parts comprising three ring-shaped light sources which project light of different hues, the highest light source being any hue other than red, to a part mounted on a PCB at different angles and heights from above, a camera to record the reflected images, and a procedure used to check the recorded patterns to determine if the soldering is acceptable.
